The cities of Helsingborg with 97,122 inhabitants and Helsingør with a population of 46,279 are separated by a mere 4 km stretch of water and a 20 minute ferry ride. Cooperations between the two cities are extensive in many fields.
The municipality of Helsingborg wants to reduce total energy consumption per inhabitant by four percent by 2010 compared to 1990, while reducing fossil fuel input to the district heating and power system by 20% in the same period. In Helsingør, the aim is for a 30% reduction compared with present standards in the gross energy consumption for heating, hot water, lighting, ventilation and cooling in new eco-houses.
The CONCERTO approach
Helsingør and Helsingborg aim to establish approximately 598 new eco-dwellings in total 74,820 m² with a saving of 25-35% in the energy consumption. The eco-dwellings are equipped with extra insulation, low energy windows and demand controlled ventilation. About 584 dwellings in total 64,380 m² are eco-rehabilitated stepwise towards high energy efficiency. Further 33,923 m² office, scool and cultural institution is included. The project will set a reference for new standards to prevail in the community both in retrofitting, new buildings, energy supply and use of polygeneration. Furthermore, the initiative will be anchored in the whole community through training of SME's, janitors corporation and trough extensive dissemination.
Specifically, a 2-9 MW wind turbines, a 5,5 MW biomass boiler using woodchips (first line of 2) and 228 m² solar collectors for domestic hot water supply and several PV plants are among the examples of the increase in RES in this community. A new type of comfort metering and control system will be introduced and a feasibility study of a potential of geo-thermal exchange and energy storage plant and possible construction will be realised.

Highlights
In Helsingborg an innovative billing procedure was implemented by the municipal housing company to motivate tenants to save energy for space heating. Flats should be rented with a given temperature of 21°C, a lower temperature leads to a discount in the rent, a higher temperature results in a rent increase.
